- SHIELDS L DALTROFF atac ic en c som September 29, 1982 Re: Docket Nos. 50-277 50-278 Insp. Report 50-277/82-14 50-278/82-14 Mr. Richard Starostecki, Director Division of Resident and Project Inspection U.S. Nuclear Regulatory Commission Region I 631 Park Avenue King of Prussia, PA 19406

Dear Mr. Starostecki:

Your letter of September 1, 1982, forwarded combined Inspection Report 50-277/82-14 and 50-278/82-14.

Appendix A to your letter addresses one item which does not appear to be in full compliance with Nuclear Regulatory Commission requirements.

The item is categorized as a Severity Level IV violation and is restated below along with our response, 1.

Technical Specification 6.13, "High Radiation Area",

j l

requires high radiation areas where the intensity of I

radiation is greater than 1000 millirem per hour to be provided with locked doors to prevent unauthorized l

entry.

Contrary to the above, about 3:45 PM on July 8, 1982, the intensity of radiation exceeded 1000 millirem per hour in the 3B Mechanical Compressor Room and the door to the room was not locked.

This is a Severity Level IV violation (Supplement IV).

Response

The violation was caused by equipment failure.

The

surveillance test which verifies-that High Radiation. doors are locked was completed' satisfactorily on the previous day, July 7, 1982.

Upon notification by.the-inspector of_the deficiency, shift personnel immediately chained and padlocked the door to j-

, control: access.

Thus, the door could not have been unlocked for more than one day.

The door locking mechanisms used at Peach Bottom on High Radiation' Area doors lock upon removal of the key.

Only a defective mechanism or the manual unlocking of the_ mechanism with-a'special key, controlled-by the Security-Supervisor, would allow the door-to remain unlocked.

Investigation revealed that the door in question had a defective locking mechanism.

This mechanism was replaced on July 13, 1982.

Health-Physics personnel have been instructed to more forcefully check the locked doors when performing the High Radiation Door Lock Survey Surveillance; Test in order to increase the likelihood of detecting potentially defective locking mechanisms.

4 If there are.any further questions, do not hesitate to-contact us.

.Very truly yours,
